Grapevine plant named &#39;CAR98-710&#39;

ABSTRACT

A new and distinct variety of grapevine plant named ‘CAR98-710’ particularly distinguished by black colored, seedless berries, medium to large berries and clusters, and excellent integrity of clusters and berries through October, is disclosed.

GENUS AND SPECIES

Vitis vinifera

VARIETY DENOMINATION

‘CAR98-710’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of grapevinebotanically known as Vitis vinifera and hereinafter referred to by thevariety name ‘CAR98-710’. The new variety originated from a crossconducted in May 1998 in Delano, Calif. between the female grapevineplant named ‘Black Globe’ (U.S. Plant Pat. No. 17,875) and the malegrapevine plant named ‘552’ (U.S. Plant Pat. No. 9,916). A single plantwas selected for further evaluation and asexual propagation.

The new variety was first propagated in December 2005 in Delano, Calif.by vegetative cuttings and has been asexually reproduced repeatedly byvegetative cuttings for 3 generations. ‘CAR98-710’ has been found toretain its distinctive characteristics through successive asexualpropagations.

Plant Breeder's Rights for this variety have not been applied for.‘CAR98-710’ has not been made publicly available anywhere in the worldmore than one year prior to filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Delano, Calif.

1. Black colored, seedless berries;

2. Medium to large berries and clusters; and

3. Excellent integrity of clusters and berries through October.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘CAR98- 710’. The data which defines thesecharacteristics were collected from asexual reproductions carried out inDelano, Calif. The plant history was taken on mature 7 year oldgrapevines grown under field conditions in Delano, Calif. All colorreferences were obtained under natural light. Color references areprimarily to the Munsell Color Charts for Plant Tissues by MunsellColor, 617 Little Britain Rd., New Windsor, N.Y. 12553-6148. Commoncolor names are also occasionally employed.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘CAR98-710’ differs from the female parent grapevine plant named ‘BlackGlobe’ (U.S. Plant Pat. No. 17,875) in that ‘CAR98-710’ has seedless,globose shaped berries, whereas ‘Black Globe’ has seeded, obovate shapedberries.

‘CAR98-710’ differs from the male parent grapevine plant named ‘552’(U.S. Plant Pat. No. 9,916) in that ‘CAR98-710’ has black, globoseshaped berries, whereas ‘552’ has red, obovoid shaped berries.

‘CAR98-710’ differs from the commercial grapevine plant named ‘AutumnRoyal’ (unpatented) in that ‘CAR98-710’ has medium to large fruitclusters and globose shaped berries maturing in September, whereas‘Autumn Royal’ has large fruit clusters and ellipsoidal elongatedberries maturing in October. Additionally, the fruit clusters of ‘AutumnRoyal’ are generally more loosely filled, have less uniformity, and arelonger than ‘CAR98-710’.

‘CAR98-710’ differs from the commercial grapevine plant named ‘SummerRoyal’ (unpatented) in that ‘CAR98-710’ is 4 to 5 weeks later maturingwith larger berries weighing 9.0 grams, whereas ‘Summer Royal’ is earlyto mid season maturing with smaller berries weighing 5.0 grams.Additionally, ‘CAR98-710’ has berry clusters that maintain integrityinto October, whereas ‘Summer Royal’ has berry clusters that shrivel(dry on the vine) beginning in late August.

I claim:
 1. A new and distinct variety of grapevine plant named ‘CAR98-710’ as shown and described herein.
